Less money and less recoil with the 308 Norma, plus the 308 Norma is, IMO one the best .30 magnums. Seriously accurate due to long case neck and better concentric bore alignment. Shorter case than most .30 Std Mags, better able to load heavy for caliber with BC advantages. Lacks in nothing, with modern powders and twist rate, it’ll push 180 gr @ 3,075 fps, 200 gr @ 2900 fps, 212 gr @ 2,850 fps and 225 gr @ 2,750 fps. With high BC bullet technology it is a real winner. Easily can take deer size game up through brown bear from close or long range. While the 358 Norma is a suburb chamber it lacks the versatility of the 308 Norma in IMO and is more in line with shooting a 375 magnum, which is fine if you like recoil, heavier rifles, stout cross bolts for stock protection under recoil, and less bullet choice versatility. The 358 Norma would make a fine, specialized guide gun for big browns, the 308 Norma is a better hunter’s field gun IMO.
